A multi-axis alignment tool including: a main body, a primary base, a puck, a first puck adjuster, a second puck adjuster, a puck retainer, a secondary base, a first pivot pin, a second pivot pin, a pivot block, a clamp head, an adjustment pin, a lock-down spacer, a first clamp finger, and a second clamp finger, wherein the multi-axis alignment tool is configured for to at least one of clamp, align, and position a work part in three axes.

A pneumatic clamping component includes a clamping member having a main body portion, an abutting portion, and clamping arms. Each clamping arm has a connecting portion and a clamping portion. A base has an accommodating cavity in communication with an air opening. The abutting portion, the clamping arms and an inner wall of the accommodating cavity jointly form an air chamber in communication with the air opening. The air opening is used for entry of air and keeps the air in the air chamber. The clamping portion is located outside the air chamber. A gap is located between the two clamping arms. When the air does not enter the air chamber, two clamping portions are not in contact with the to-be-clamped object. When the air enters the air chamber, a to-be-clamped object is located in the gap, and the two clamping portions clamp the to-be-clamped object.

The apparatus (1) for clamping workpieces on machine tools comprises: 1 a basic frame (2) attachable to a machine tool (M) for machining a workpiece (P); a first clamping assembly (3) and a second clamping assembly (4) movable between a release position and a clamping position of the workpiece (P); a fluid actuator (5, 6), provided with a fixed portion (5) and with a movable portion (6) connected to a drive assembly (7) associated with the clamping assemblies (3, 4);
wherein the drive assembly (7) comprises a rocker element (9) associated in a rotatable manner with the movable portion (6), which comprises at least one curved thrust surface (10) arranged in thrust contact against the rocker element (9), wherein the rocker element (9) is rotatable on the curved thrust surface (10).

The present disclosure concerns a set for the production by 3D printing of implant abutments for dental implants, the set including at least one abutment having an elongated base member with an axis, and at least one positioning element fixed to the base member; a plate with at least one recess and a locking portion; where the recess is larger than the elongated base member and where the locking portion is configured to be in a form fit connection with the positioning element in order to vertically position the abutment, and lock the abutment in rotation around its axis.

A rotary head plate having a first precision surface and a second precision surface. The rotary head plate mounted to the first sub fixture. A second sub fixture being able to freely rotate with the rotary head plate when rotated. A tailstock plate mounted to the second sub fixture. The tailstock plate having a first precision surface and a second precision surface, A first head plate attached to the first precision surface of the rotary head plate and the first precision surface of the tailstock plate. A second head plate attached to the second precision surface of the rotary head plate and the second precision surface of the tailstock plate. The first head plate and second head plate adapted to each receive two cylinder heads. The first head plate and second head plate each including at least one cylinder head opening.

This processing device is provided with: a tool for machining a workpiece W along the thickness direction thereof, the width-direction external shape of the workpiece W being substantially finished; and a flexible vice 7 that clamps the workpiece W in the width direction without clamping the workpiece W in the thickness direction. The flexible vice 7 is provided with a position adjustment mechanism that prevents the position of the workpiece W from changing in a plane along the width direction before and after the workpiece W is clamped. The present invention is provided with a rough processing tool for performing processing at a rough-processing position, a finishing processing tool for performing processing at a finishing-processing position, and a control unit that causes the position adjustment mechanism to move between the processing performed by the rough processing tool and the processing performed by the finishing processing tool.

When a workpiece holder holding a workpiece is rocked around a lateral rocking axis by a work stage of a mounter and the workpiece is positioned so that one mounting surface of the workpiece faces a predetermined direction to be worked, a component is mounted on the one mounting surface by a mounting head of the mounter. When a posture of the workpiece in the workpiece holder is changed by a posture changing head of a posture changer and thereafter the workpiece holder in which the posture of the workpiece is changed is rocked around the lateral rocking axis by the work stage of the mounter and the workpiece is positioned so that the other mounting surface of the workpiece faces a predetermined direction to be worked, a component is mounted on the other mounting surface by the mounting head of the mounter.
